None of the three radial pulsators we tried with Swift were detected,
in spite of having been selected among those showing the strongest H\(\alpha \) 
and H\(\beta \)  emission on GALAH spectra (far stronger than typically observed
in acc-SySt). This supports the clear-cut role of satellite UV
observations in segregating acc-SySt [1]}, in
particoular from radial pulsators of similar spectral appearance on optical
spectra.
